FURNAGE.

Application led February-20, 1925. Serial No. 10,623.

This invention relates to new and useful improvements in heat-ingsystems and more particularly to a combination of hot water and hot airheating system. The main ob ject of my invention is the provision of aheating system combining both hot air and hot water whereby to utilizethe maximum amount of heat for minimum amount of fuel used.

Another object of my invention is the provision of a heating systemwherein the usual conveyors for the hot water and hot air are soarranged relative to the heating plant as to utilize a. maximum amountof heat from the fuel consumed and convey the hot air and hot water tothe interior of the building to be heated.

Another object of my invention is the provision of a heating systemwherein the smoke and heat from the burning fuel is utilized to thefullest extent before being passed out through the vusual smoke stack soas to provide for thoroughly heating of the hot air conduits and hotwater conduits.

AWith the above and other objects in view, my invention consists in thenovel features of construction and the combination and arrangement ofparts to be hereinafter more fully described, pointed out in the claimsand shown in the accompanying drawings, in which:

Fig. 1 is a longitudinal sectional view of a device constructed inaccordance with my invention, parts thereof being shown in elevation,

Fig. 2 is a front elevation,

Fig. 3 is a transverse section on the line 3 3 of Figure 1, and

Fig. 4 is a detail section on the line H of Figure 1.

Referring now more particularly to the drawings, the numeral 1indicatesthe furnace in which the fuel is burned and adapted to beinserted in the furnace through the lire door 2. The furnace is providedwith an ash door 3 whereby the ashes may be readily removed from thefurnace. The interior construction of the furnace such as the grate andthe like are immaterial relative to improved system, but that type offurnace having a water jacket et is essential, said water jacketextending upwardly and over the tcp of the furnace, as shown at 5 andprovided with a head 6. The smoke conduit 7 is con- 55 nected to thehead 6 and extends upwardly at an angle in the air chamber 8 into a head9 which receives the smoke and heat and then diverts the same in anopposite direction on an inclined angle into the conduit 60 10, theupper end of which has communication with a smoke stack 11. From this itwill be apparent that the heat and smoke from the burning fuel in thefurnace 1 is caused to travel a considerable distance before enteringthe smoke stack 11. and thus the conduits 7 and 10 will be thoroughlyheated to throw off enough heat to heat the air in the chamber 8. rllhischamber 8 is formed of a large casing 12 supported upon 70 the top ofthe furnace.

The head 9 of the smoke conduits 7 and 10 is supported by means of apillar 13 which extends through an opening in the bottom of the casing12.

The hot water from the jackets d and 5 is diverted into the pipes 14arranged in the inclined smoke and head conduit 7 with the lower endscommunicating with the water jacket at 15. The upper ends of these pipes14 communicate with the reservoir 16 arranged in the head 9, thisreservoir receiving the water from the pipes 14 and diverting it intothe upwardly inclined pipes 1'? which extend in divergent relationrelative S5 to the pipes 14 in the smoke and heat conduit 10 andcommunicate at their upper ends with a head or reservoir 18 arranged inthe upper end of the conduit 10 at a point adjacent the entrance to thesmoke stack 11. From this arrangement it will be apparent that the waterin the pipes 14 and 17 will be thoroughly heated before passing into thehead or reservoir 18. The reservoir 18 is connected with the radiatorsor other 95 suitable heating elements in the building by means of asupply pipe 19 while the chamber 8 may be connected in any suitablemanner to the hot air registers through the medium of a conduit 20whichopens outwardly from 100 the top of the hot air chamber 8 at apoint adjacent the smoke stack 11.

It will be apparent from the foregoing that by arranging the water pipes1ein the smoke and heat conduits 7 and 10 the 105 water therein will besubjected to the full amount of the heat from the fire in the furnace 1and cause the water to flow around through the pipes in the conduitswhich provide for thorough heating of the water before the same passesout through the supply pipe 19.

It will also be apparent that by causing the heat and smoke to traveltl'irough the di-n vergent conduits '7 and 10 they will be heated andradiate considerable heat therefrom into the air chamber 8 and theheated air will then pass out through the conduit 20.

To permit the circulation of air through the air chamber 8 to pass inheated condition through the conduit 2() it is necessary to provide acold air inlet. This cold air inlet is indicated at 8 in Fig. 1 of thedrawings and preferably, but not necessarily, passage through this inletAis controlled by a shutter plate 9 of a well known construction.

In order to create the proper circulation of the smoke and heat as itrises from the furnace 1, an air opening 21 is fori'ned in the front ofthe furnace near the top thereof and in alignment with the lower side ofthe conduit 7, thus creating proper drift toward the smoke stack 11.

In order to provide means whereby to clean the conduit 10 a similar'opening E22 is provided normally closed by means of a swinging door 23.

Attention is also directed to the arrangement of the reservoir 16 in thehead 9, as it will be apparent that this reservoir receives the heatdirect from the furnace 1 and that the water coming into the reservoirfrom the pipes 14 will be maintained in a highly heated conditionbefore. passing upwardly through the pipes 17 and will be retained in ahighly heated condition upon reaching the reservoir 18 prior to beingpassed out through the supply Vpipe 19. Any suitable means may beprovided for conveying the supply of water to the water jackets 4 and 5.

From the above it will be apparent that I have provided a combination ofa hot air and hot water heater wherein the full heating capacity of afurnace is utilized and a building may be provided with both a hot airand a hot water heating system in accordance with my idea.

It will be noted that as the water has passed through the usualradiators it is returned to the water jacket 4 in any desired manner anddirected through the openings 4a in the bottoni of the furnace as shownin Figure 2 so as to provide for continuous circulation of the water.

While I have shown and described the preferred form of my invention, itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice without sacrificing any of the novel features ordeparting from the scope of the appended claims.
